 Hey guys. I'm developing a Dialog based application. I need that the main window (a CDialog derived) stays initially hidden. How can i do it? I've been tried checking off the option "Visible" in the resource editor and it doesn't work. I've been tried calling ShowWindow(SW_HIDE) in OnInitDialog() function and it doesn't work. I've tried ModifyStyle(WS_VISIBLE, 0) in OnInitDialog() and it doesn't work. I've tried this:

      lpCreateStruct->style&= ~WS_VISIBLE;
      if (CDialog::OnCreate(lpCreateStruct) == -1)
            ....

in OnCreate(...) function and it doesn't work.

Thanks in advance,

Jose.

Is it an OCX? Why do you need to hide the appliction which U have just execute?
Anyway maybe the HideApplication() function will help U .

If it is an OCX, it probably wouldn't be dialog based...

Try this (put in the InitDialog function):
SetWindowPos (NULL, 0, 0, 0, 0, SWP_HIDEWINDOW);

if that doesn't work, try this:
SendMessage (WM_SHOWWINDOW, FALSE, 0);

Let me know how that works...

Edit your C...App::INitInstance()
Replace
CYourDlg dlg;
if( dlg.DoModal() )
...
return FALSE;

to be

CYourDlg * pDlg = new CYourDlg;
pDlg->Create( CYourDlg::IDD );
m_pMainWnd = pDlg;
pDlg->ShowWindow( SW_HIDE );
return TRUE;

and you won't see your dialog anymore. I garuntee.

This solution is not valid for me because:
- I need to hide the main dialog but i create a notify icon. The user can show the dialog double clicking in this notify icon.
- Once the user has showed the main dialog, the application doesn't end clicking the X button.

Thanks.

Hi!
Here is your answer :
Replace  your Application Class's InitInstance  code

CCurrentDlg dlg;
if( dlg.DoModal() )
.
return FALSE

With

CCurrentDlg * pDlg = new CCurrentDlg;
pDlg->Create( CCurrentDlg::IDD );
m_pMainWnd = &pDlg;
pDlg->ShowWindow( SW_HIDE );
return TRUE;

I think it will work. Let me know if you want more explanation.

majorjohn was right:
If your main wnd is a dialog it mast be a modaless

Here is code:
CCurrentDlg dlg;
m_pMainWnd = &dlg;
if( dlg.DoModal() )
      return FALSE

you can track into the DoModal func
and you'll find the DoModal just create a modaless
dialog.
